Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

I have all the same. But, I tried to run SmathStudio through the debugger in the Mono Develop and it works as expected. It is possible that this is a bug in the libraries of mono for Raspbian (imho) Edited by moderator 28 August 2017 01:07:17(UTC)

The problem was solved by updating mono from version 3.2.8 to version 5.2.0.215. The upgrade described here: https://blog.luppes.com/2015/03/19/mono-on-raspberry-pi/
$ mono --version Mono JIT compiler version 5.2.0.215 (tarball Mon Aug 14 16:25:12 UTC 2017) Copyright (C) 2002-2014 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com TLS: __thread SIGSEGV: normal Notifications: epoll Architecture: armel,vfp+hard Disabled: none Misc: softdebug LLVM: supported, not enabled. GC: sgen (concurrent by default)
While SmathStudio works as expected.
